Answer to Question #80165 in Physics for TIGER

Question

c) In a circular accelerator a proton is accelerated to an energy of 10*12 eV, as measured
in the laboratory frame. If the rest energy of the proton is 10*9 eV, calculate
i) the speed of the proton as measured in the laboratory frame
ii) the force that must be applied by the magnets in the accelerator to keep the
protons moving at this speed in a circle of radius 1000 m.
